“Not enough memory” on Xiaomi: 7 proven ways to free up space

The message “Not enough memory”** on Xiaomi, Redmi or POCO smartphones appears unexpectedly: you can not install an update, download a photo from the messenger or even save a screenshot. The reason lies not only in the filled storage — often to blame system debris, app cache or errors in the work of MIUI. In this article, we will analyze the unique cleaning methods that work even when standard methods do not help.

The problem is relevant for all models: from budget Redmi 9A Xiaomi 14 Ultra flagships, but approaches are different - somewhere it is enough to delete the cache, and in advanced cases you will need to transfer data to the main mobile phone. SD-We tested each method on real devices and identified those that have the maximum effect with minimal risks.

Why Xiaomi is showing “Not enough memory” when there’s room

The error often occurs when free space does not meet the requirements of the system, for example, to update MIUI you need at least 1.5-2 GB of free space, even if you are trying to install an update weighing 500 MB.

• 📱 Reserved space: MIUI It blocks up to 3-5 GB for system needs (updates, logs, temporary files) and this data is not displayed in the standard storage menu.
• 🗑️ Hidden cache: Apps (especially Facebook, TikTok, Google Play Services) create temporary files that are not automatically cleared.
• 🔄 Memory Fragmentation: After multiple installations/deletions, free space is “split” into small blocks that the system cannot use effectively.
• 🛠️ File system errors: Damaged sectors of the drive (especially on older models with eMMC 5.1) lead to incorrect display of free space.

Interestingly, on smartphones with UFS 3.1 (such as the Xiaomi 13 Pro), the problem is less common due to optimized memory management, while owners of devices with eMMC (such as the Redmi 8A) have to clean memory 2-3 times more often.

Method 1: Deep Cleaning through “Security” (Hidden Functions)

The standard Settings menu → Memory does not show all files. To remove system debris that is not visible to the user, use the built-in MIUI tool:

1. Open the Security app (the shield icon).
2. Go to the Cleanup section. → Deep cleaning.
3. Click Scan and wait until it is completed (may take up to 5 minutes).
4. Choose all categories in the results, especially: 🗃️ Residual files (remains of remote applications). 📁 Cache of mini-programs (junk from widgets) MIUI). 🔍 Log files (system logs, up to 1 GB).

Clean up

Important: After deep cleaning, some apps (such as WhatsApp or Telegram) can take longer to load when you first run – this is normal, as the cache is recreated.

Method 2: Manually clean the cache for each application

Some programs (e.g. Facebook, Instagram, YouTube) accumulate cache of up to 500 MB-1 GB each. Standard cleaning through Settings → Apps are not always effective. Here's how to do it correctly:

1. Go to Settings → Applications → Application Management.
2. Sort the list by size (click on the three dots in the top right corner → Sort by size).
3. Select an app with a large cache (like Google Play Services or Mi Video).
4. Click Warehouse → Clear cache and Clear data (unless the application is critical).

Instructions for transfer:

1. Put it in. SD-map (recommended class) A2 or UHS-I speed).
2. Go to Settings → Storage → Internal Memory.
3. Select a category (for example, Photos and Videos) → Move it to SD-map.
4. Confirm the action and wait until it is completed (may take up to 10 minutes).

⚠️ Attention: If you pull out SD-The card without Safe Extract (in the storage menu), files can be corrupted. Also, do not use the card as internal memory (the option is to format as internal) - this slows down the smartphone by 20-30%.

Method 4: Remove duplicates and unnecessary files via Files by Google

The built-in MIUI Explorer can’t find duplicates and large files, but it’s better to use third-party tools like Files by Google (the official Google app):

1. Install Files by Google from the Play Market.
2. Open the application and give access to the files.
3. Go to Cleanup → Duplicate files or Large files.
4. Select unnecessary files (such as repetitive screenshots or old videos) and click Delete.

Examples of things that can be safely removed:

• 📸 Screenshots older 3 months (usually in the /Pictures/Screenshots).
• 🎬 Videos from messengers (for example, WhatsApp/Video or Telegram/Video).
• 📄 APK-files (remainders of installed applications in /Download).
• 🔊 Voice messages (take up little space, but there are hundreds of them – up to 1-2 GB in total).

Method 5: Reset partition cache (without data loss)

If previous methods didn’t work, try resetting the Wipe Cache Partition, which won’t delete your files or apps, but will clear temporary system data that may be blocking memory.

1. Turn off your smartphone.
2. Press the Power button + Volume up until the Mi logo (Recovery mode) appears.
3. Use volume buttons for navigation and power button for selection.
4. Choose Wipe & Reset → Wipe Cache.
5. Confirm the action and wait for the completion.
6. Reboot the device (Reboot).

What does it mean?

• ✅ Frees up to 500 MB-1 GB of hidden cache.
• ✅ Resolves update errors MIUI.
• ✅ Corrects freezes when installing applications.

⚠️ Warning: Don't confuse Wipe Cache with Wipe Data! The second option will delete all your data, including photos, contacts and apps.

Method 6: Completely reset your settings (if nothing helps)

If the smartphone still shows "Not enough memory" even after all the manipulations, the last resort is a factory reset, which will remove everything, including:

• 📱 Installed applications and their data.
• 📸 Photos, videos and music (if not on the list) SD-map).
• 📞 Contacts, SMS Call logs (if not synced with Google).
• 🔐 Wi-Fi passwords and system settings.

How to reset correctly:

1. Back up important data (via Settings → About Phone → Backup or manually on PC).
2. Go to Settings → About the phone → Reset settings.
3. Choose to erase all data and confirm.
4. After the reboot, set up your smartphone as new.

Important: On models with MIUI 14 and newer, you may need to re-assign your Xiaomi account after a reset (if Device Protection was enabled).

💡

Resetting is the only way to return a clean file system if memory is clogged due to viruses or MIUI errors.

How can we prevent the error from recurring?

To prevent the problem from returning in a week, follow these rules:

• 📵 Turn off auto-update apps in the Play Market (or limit updates to Wi-Fi only).
• 🗑️ Clean the cache once a week through Security → Cleanup.
• 📥 Set up automatic file upload to the cloud (Google Photos, Mi Cloud).
• 🚫 Do not install apps from unknown sources – they often contain hidden debris.
• 🔄 Regularly reboot the smartphone (once every 2-3 days) to clear the operational cache.

For models with 32 GB of memory (for example, Redmi 9C) we recommend:

• Use cloud services to store photos/video.
• Install lightweight versions of applications (Facebook Lite, Messenger Lite).
• Opt out of music caching in Spotify/YouTube Music.
